To all whom it may concern;

Be it known that I, THOMAS WILLIAM Han LIWELL, a subject of the Queen of Great Brit ain, residing-in Bi ighouse? county of York,

England, have invented certain new and usel {m Improvements in Glazed Roofs, of which the following is aspecification.

' This invention is the subject of patents in Great Britain, dated J uly 8, 1884, No 9,888, (which covers the construction shown in Figs.

1 to 7ofthe accompanying drawings) and May 8,1885, No.'5,684, (which covers the-constrnction shown in Figs. 9 andthereof.) This invention has reference chiefly to glazed roofs, although it applies in part to metal roofs or roofs of other-materials, as well as to sides of buildings or other structures.

,In the'accompanying drawings, Figure l is a perspective view of a fragment of ,a glass roof constructedaccording to my invention, showing the glazing-bar or rafter and the joint between this bar and the opposite sheets of glass in transverse section. Fig. 2 is a cross-section of the sealing-strip before being applied to'the joint, and Fig. 3 is a cross-section thereof after being applied. The remaining figures illhstrate modifications. Figs. 4, 5. 6, and 7 are .perspective views on a smaller scale than Fig.

30. construction of the sealingstrip. Fig. 9 is a 1, showing different constructions of glazed roofs. Fig. 8 is a cross-section of a modified perspective view of another modified construction of glazed'roof, and Fig. ,10 is a view of the sealing-strip-used therewith. In Fig. 1, let A designate one of the inclined glazingbarsof the roof, and B B the sheets of glass. The bar Ais made in two pieces, or of two bars j oined together sideby side by screws d at intervals, or by other suitable means. The bar or rafter Ais formed on its opposite sides with ledges a a, on which rest the edges of the glass sheets. In these ledges are formed grooves or gutters b b, which carry away any leakage through the joint. 0n the sidcsof the,

placed an angle-strip, k, of sheet metal.

above the ledges a a and above the glass, and along the middle of its projecting portion, let- 1 tered O, is cut a deep, narrow groove,'e, which is cnlarged at its bottom. 1

D is a sealing-strip, of lead, zinc, or-other suitable metal or material, of Y shape in cross- 5 section. In this construction iti s made from a strip or ribbon of metal by bending the lat ter along its middle, bringing the side portions together face to 'face, and turning the edge portions away from each other, as shown in Fig. 2. The middle portion-is not creased flat, but is bent with a gentle curve, (as though bent around a wire,) thus forming a head, or head, or enlargement), at the bottom of the Y: This Y-shaped strip D is inserted into the groove 2, its head f filling the enlargement at the bottom of the groove, its body 9 (Fig. 2) filling the groove up to the surface of the glazingbar, and its wings h h (Fig. 2) projecting above 7 the bar. When the sheets of glass have been laid in place, these wings h h are turned down over the projecting portion 0 of the glazingbar until their edges bear upon the glass and hold it down in place, as shown in Fig. 1.- Fig. 3 shows the shape which the strip'l) then assumes.

The Y-shaped strip i made of soft metal, in order that when thus bent down it will re main in place. The lifting of the sheets of glass by pressure from beneath is prevented by the head f-on the strip D, which is too large to pull out of the groove e.

In Figure l is shown an additional feature of my invention. .Before the wings h hare bent down there is inserted along each edge 8 of the glass, and against the projecting portion 0 of the glazing-bar, a piece of felt, t, or other soft and yielding or absorbent material, which is bent into L shape, and over this is Then the wingsh h are bent down over the anglestrips 7c 7., thus holdingall securely in place and making awater-tight joint. The outer edges of theangle-strips kin are turned down into contactwith the glass, thereby in- 95- closing and concealing the feltt' tand prcventing the escape or displacement of the latter.

The angle-strips k k 'may'be fastened to the When the roof is made with overlapping sheets of glass, as shown, some construction must be provided/for preventing the slipping downof the sheets of glass. To this end I j I make the angle-strips k k only as long as the exposed portions of the sheets of glass, and I turn up their upper ends, as shown atl in Fig.

1, to form a stop against whichthe lower edge of the next sheet of glass above may abut. This effectually prevents the slipping down of the glass, since the strips k, by being fastened sheets of-glass above, to prevent their slip-' ping down.

may be used in place of or under the strips of concealing the wood or putty.

to the portion 0 of the glazing-bar, cannot be displaced. Thus to each joint as many'strips k k are used as there are sheets of glass; but by preference only one strip D is used, this being continuous from the ridge to the caves, or from the top to the bottom of the skylight. Underneath the glazing-bar is fastened a metal strip, E, having grooves along its opposite edges forming gutters m m. These are supplementary to the gutters b and c, and the metal strip imparts a desirable finish to the under side of the glazing-bar.

I will now proceed to describe some modifications of my invention applicable to glazed roofs.

Fig. 4 shows a construction wherein the glazing-barA is made of only one piece, in

7 from the top, and consequently itshead f,

Fig. 2, is unable to prevent the pulling out of the strip. Hence, in order to hold the strip securely down in the groove nails or screws n n are passed through the portion-C and the body 9 of the strip D. After the sheets of glass B B have been laid strips of wood k k are laid upon them against the projection O, with,their upper ends against the edges of the Putty or other'plastic material wood. Finally, the wings h h, Fig. 2, of the strip D are'turncd down over the wood or putty Zak, with their edges on the glass, thus This view shows two strips, D D, the upper one being lapped over the under one.

i Fig. hshowsa glazing-bar madein two pieces. The strip D is made somewhat wider, and its wings h h'are turned down over the sides of the projection O, and its edgeseigtend onto the surface of the glass for a short distance.

; Fig. 6 shows a glazing-bar, A, of sheet metal,

formed around a wooden or metal core or rafter, A. The metal is bent to form the ledges a a and gutters b and c, and the wooden core has the groove 6 formed in it, which maybe ent'red by the sheet motel forming the glazing- .bar or not, as, preferred. If the glazing-bar is made in two parts, they will be fastened to 1 the wooden core by screws d d. v The metal strip D is inserted and turned down in the same manner as already explained. I

Fig. 7 shows a modified construction wherein the glazing-bar is made of sheet metal wrapped around a metal core. The coreA is a bar, of rollediron or cast-iron or other metal, with a flange at its bottom, around which is wrapped the sheet metal, which is. formed into a ledge, a, and gutter, b, and the two edges of which project upward. to form the projection G and '.,stand close together, the narrow space between them forming the groove or opening c to 'receive thebody g of the strip D. Screws, nails, rivets, or small bolts and nuts are passed through the 'metal plat-es to hold the strip 1) in place. When the glass is set, the wings h I- are turned down upon it, as shown.

In all its variousforms or modifications my invention has the advantage, as applied to glass roofs, of makinga neat and tight joint with but little labor and by a simple construction, in-' volving but few parts. The employment of i the strips D of ductile metal makes the replacing of broken panes of glass to be very readily effected by merely turning up the wings, removing, the broken glass, inserting a new pane, and turning the wings down to theirplac'e aggin.

It is not essential that the sealing-strip be made of a strip of sheet metal doubled upon itself, as described, although this is preferable.

Fig 8 shows the sealing-strip made with its head f and body portion 9 solidfor of one thick ness, Such a strip without the head f is not novel with me. p r

Fig. 9 shows a glazed roof embodyinga portion of my invention. The glazing-bar-A has no groove 0, but instead this groove or openin g is substantially formed in the sealing-strip D, (shown in Fig.10.) The body portion g ofthis strip is divided into two portions or flanges, g g, with a space or opening, e, between them wide enough to receive the projection C. Nails or rivets are put thgough, as at n, to hold the When the glass has sealin strip in pl r g mwingsh h of thesealingbeen laid in place,

'strip are turned down ripon it, as clearly shown.

My invention is not wholly confined to glazed roofs, but is in part applicable to certainkinds of metal roofing, such as roofs of sheet-lead, vzinc, copper, tin, or other suitable roofing material. The metal sheets or plates are to be laid in place of the glass plates shown, it being preferable to turn up their, lateral edges against the bars A, as is customary in other metal roofs heretofore made. A roofesheathing may be supplied to support the metal plates if found desirable. i

By the novel constructionsot' roofing provided by my invention I avoid the use of bolts, screws, or nails,which are accessible to the weather or to moisture, and make a joint which presents no external fastenings, and no holes or seams through which leakage may occur. Thejoint is readily sealed, and may-b5 I 25' tially as set forth.
